IMPROVEMENT IN ROLLER-BRACKETS FOR SCRE ENS.

Specification forming part of Izetters Patent No. 219,321 a d September 2, 1879; application filed J annary 27, 1879.

To all whom it may concern:

Be it known that I, JOHN G. STEWART, of Garlinville, in the county of Macoupin and State of Illinois, have invented a new and 1mproved Roller-Bracket for Screens; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the accompanying drawings, forming part of this specification, in which- Figure lis a perspective view, showing the bracket applied to a screen-frame; and Fig. 2 is a vertical section of the bracket.

The invention consists in an improved rollerbracket for attachment to the corners of photographic and other screens, for the purpose of supporting them and facilitating their movement on the floor.

The construction of the device is as hereinafter described.

The. body of the bracket A consists of an angular socket formed of two flanged parts, a a, which are joined at a right angle. In this socket the corner of the screen B is secured by bolts passing through holes in the parts a a, as shown.

The other portion of the bracket consists of lateral wings or arms b b, which extend in 0pposite directions from the vertical portion a of the socket, and in a plane at right angles to the screen. The casters 0 c are permanently attached to the ends of the arms 12 b.

The above-named parts, save thecasters c 0- namely, the flanged socket a a and arms I) b are cast in one piece, thus combining strength with economy of material and compactness of form.

The device is light, cheap, ornamental, and highly useful for its purpose.

I do not claim an angular flanged socket or corner-piece for screens or other frames; and I am also well aware that screens have been supported by brackets consisting of an arched or bent piece of wood mounted on casters, and having mortises to receive the tenons of the screen-frame.

What I claim 'is- As an article of manufacture, the improved screen-roller bracket formed of the angular flanged portion or socket a a and the lateral arms I) b, all cast in one piece and the casters attached thereto, as shown and described.

JOHN GUISE STEWART.
